鉴于基于表演的动画技术非常直观自然，因此特别适合新手以及非专业人员使用，已在近些年受到了重要关注。但是已有的基于表演的动画系统，或是需要特殊的交互设备，或是只适合于低自由度的物体的动画，比如刚体动画。针对这一问题，提出了一种新的基于表演的动画技术，并根据该技术开发了一个2维角色动画系统。它可使用笔作为道具，实时地把笔的运动映射到动画角色上，而角色的运动过程被录制下来即生成动画。评估结果表明，该系统降低了动画制作的门槛，让非专业人员也可以简单快速地创作角色动画。

Performance-based animation has received significant attention because of its naturalness, intuition, and its easy-to-use for novices and non-professional animators. However, most existing performance-based systems either require special and expensive device or can only animate low degree of freedom objects such as a rigid body. This paper presents a new performance-based animation technique for novice animators and develops a 2D character animation system. It uses a pen as the prop and maps its movement to the character in real-time, the character’s motion is recorded to form an animation. The evaluation result shows that the system lowers the barrier of animation authoring and allows novices to create animation simply and quickly.
